In the wise words of Benjamin 'Senor' Chang "HA, GAY~EEEEEE!"
Jokes aside, looking at the cover photo for the Manga, and how they are not family, so far, and how they have their fingers are entangled, is very romantically suggestive. also to be honest, I thought the character of Anis was Man what with her chest being not as pronounced as the other woman's, and no I don't mean that as an insult, I find too many characters busts are distractingly big in Anime/Manga, so I tend to appreciate the more fit or lithe designs like Rukia Kuchiki and the many gems in 'Land of the Lustrous.' At the end of the day, everyone has their preferences.
I've enjoyed each of the Arcs of Love and Loss to this point and I believe I'll enjoy what is in store for the lonesome Bride we have now.
